United States Patent FLOOR DRAIN MASTER Thomas N. Scoville, New York, N. Y. Application October 13, 1952, Serial No. 314,469

2 Claims. (Cl. 182-31) This invention relates to floor drains.

It is an object of the present invention to provide a floor drain adapted to meet any drainage problem, the units being available with drain-holes in any or all four sides and bottom surface, to meet any drainage requirement.

It is another object of the present invention to provide a floor drain in which all of the parts fit easily together, the assembled units being designed to give heavy-duty service under normal conditions.

It is still another object of the present invention to provide a floor drain designed in standard units which fit together in a slip-joint manner, these units being adapted for driveways, roads, garages, power plants, food and chemical plants, laundries, basements, factories, institutions, barns, stables, ducts, heating pipes, septic tanks, and junction boxes.

It is still another object of the present invention to provide a floor drain which anyone can install, no special tools being required, and which are easy to clean by merely removing the top.

It is still another object of the present invention to provide a floor drain which can be set directly in earth or concrete, it being unnecessary to build special forms, and which will sustain heavy loads.

Other objects of the present invention are to provide a floor drain bearing the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is compact, durable, easy to assemble and elficient in use.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a perspective view of a floor drain embodying the features of the present invention and shown assembled;

Fig. 2 is an exploded view in perspective of the parts comprising the invention;

Fig. 3 is a perspective view of the invention shown installed under a house rain-gutter;

Fig. 4 is a perspective view of the invention shown installed across the floor of a barn or stable and Fig. 5 is a perspective view of the invention shown installed across a driveway.

Referring more in detail to the drawing, in which similar reference characters designate corresponding parts throughout the several views, there is shown a floor drain, referred to collectively as 10, including a rectangular body 11 of the same heavy duty iron as used in city sewers and manhole covers open at the top and both ends.

The top edges of body 11 are integrally formed with flanges 12 providing shoulders 13, substantially as illustrated, the flanges 12 being reinforced by integrally formed brackets 14.

A slightly convex cover 15 having spaced openings 16 is adapted to rest upon the shoulders 13 intermediate the flanges and to be retained therein by its own weight, the cover being formed of heavy duty iron. It will be noted that the length of the cover 15 is slightly less than the length of the body 11 for a purpose to be here inafter referred to.

The body 11 at one end is provided with a threesided recess 17 extending from one shoulder 13 to the other adapted to snugly receive a separable, T-sh'aped end 18 of heavy duty iron therewithin, substantially as illustrated in Fig. 1. It will be noted that when the end 18 is assembled with the body 11 as shown in Fig. l, the inner surface of the top edge 19 of end 18 will abut one end 20 of cover 15.

A similarly shaped end 21 is provided for the other end of body 11, this end 21 being slightly larger than the end 18 whereby to coincide with the end of body 11, substantially as illustrated in Fig. 1. This separable end 21 will be retained against the other end of body 11 by the surrounding earth or concrete or by an adjoining drain unit (see Figs. 4 and 5).

It will be apparent that the above floor drains when assembled will be adapted to fit together in a slip-joint manner with ends 21 adjacent the ends 18 of the adjacent floor drain, as shown in Figs. 4 and 5.

As shown in dotted lines in Fig. 2, drain-holes 22 may be provided in any or all four sides and bottom surface to meet any drainage requirement. The drain pipe or tile is fitted to the flanged drain-holes 22 at the points where it starts to carry away the water.

In the form of the invention shown in Fig. 3, only the bottom surface of body 11 is provided with a flanged drain-hole 22, the unit being installed under a house rain-gutter 23 with a drain pipe 24 connected to drainhole 22, not shown, and carrying 01f the liquid to a final disposal ditch, not shown. Here the ends 18 and 21 are retained in place by the earth surrounding the unit.

In the arrangement shown in Fig. 4, only the end 18 is provided with a flanged drain-hole 22, the units 10 fitting together in slip-joint manner substantially as illustrated. These units are shown installed across the floor of a barn or stable, a drain pipe 24 being connected to the drain-hole and carrying off the liquid to a final disposal ditch or dry-well, not shown. Here the units are retained in an assembled position by the surrounding concrete.

In the arrangement shown in Fig. 5, the units are similarly assembled across a driveway 25, with only one of the units having a flanged drain hole in one of its sides. A drain pipe 24 is connected to this drain hole and runs to a disposal ditch 26. In this arrangement, the intermediate ends 18 and 21 are provided with nonflanged drain-holes permitting the liquid to flow from one unit to the other, this also being true of the arrangement shown in Fig. 4.

To clean the units, the removable tops 15 are easily lifted, it being unnecessary to remove any screws or nuts during this operation. The flanged drain-holes 22 allow only liquids to flow through, preventing clogging of drain pipes 24. The above easy cleaning removes all sludge and odors.

These units may be installed across straight or curved driveways, with drain pipe or tile carrying water underneath driveway to culvert. They may also be installed around basement or garage walls with drain pipes or tile carrying water to disposal ditch or dry-well.

It should now be apparent that there have been provided floor drain units adapted-to be used singly or in combination and which have drain pipe connections to provide pipe or tile outlets for every type of installation.

While various changes may be made in the detailed construction, it will be understood that such changes shall be within the spirit and scope of the invention as defined by the appended claims.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

l. A drain unit comprising a substantially rectangular body open at the top and both ends, an outwardly and then upwardly extending flange secured to each top edge of said body extending substantially the length of said body, whereby to provide a shoulder along each of said upper edges, said body at one end being provided with a three-sided uninterrupted recess of substantially U-shape about the inner vertical faces of the side walls and horizontally across the bottom extending from one of said shoulders to the other, a separable, substantially T-shaped end closure adapted to fit snugly within said recess, a second separable substantially T-shaped end closure adapted to abut and coincide with the other end of said body, said second closure being slightly larger than said first end closure, a slightly convex cover having a plurality of spaced openings adapted to rest upon said shoulders intermediate said end closures, and means interconnecting the unit with a drain pipe.

2. A drain unit according to claim 1, said means interconnecting the unit with a drain pipe comprising a flanged opening provided in the bottom of said body, said flanged opening being adapted to receive the end of the drain pipe.
